Frustrating night

Down like 2-3 buyins after playing 3500+ hands of NL50 6-max on FT today. I thought I had been playing too cautiously lately so I tried to be more aggressive and pick my spots today, and I think I played well for the most part but not much went my way. Here are some hands:

1) I almost never slowplay sets on the flop but this seemed like a good time. Bit me in the ass, too.

2) Villain was playing 38/16...thoughts?

3) I'm so bad.

4) Aces go down in flames yet again.

5) Don't even know what I'm doing here.

6) LOL Quadaments I play so bad why am I calling the turn and playing so weak.

My aces also lost to Q9o but I'm sick of posting stuff so let's just call it a night. Good luck at the tables all,
